Dispersed Communication by Central Bank Committees and the Predictability of Monetary Policy Decisions

The paper asks whether members of central bank decision-making committees should communicate with the public in a collegial manner, by conveying the consensus or majority view of the committee, or in an individualistic way, by providing the diversity of views among the committee members. It finds that more active as well as more consistent communication by committee members improves the predictability ...

A New Approach for Assessing Sleep Duration and Postures from Ambulatory Accelerometry

Interest in the effects of sleeping behavior on health and performance is continuously increasing - both in research and with the general public. Ecologically valid investigations of this research topic necessitate the measurement of sleep within people's natural living contexts. We present evidence that a new approach for ambulatory accelerometry data offers a convenient, reliable, and valid measurement ...

Sparmotive von jungen, mittelalten und älteren Erwachsenen: erste Ergebnisse eines neuen Inventars zur Erfassung lebenslaufbezogener Sparmotive

There is some research on personal reasons for saving money in the economic sciences. However, not much is known about the age differences of saving motives. In this vein, the future time perspective (FTP) is known to play a critical role for motivation across the life span. In this study, we introduce a new Saving Motive Inventory (SMI), which also covers saving goals after retirement. Furthermore, ...

Measuring Time Use in Surveys: Concordance of Survey and Experience Sampling Measures

It is still unclear to what extent time allocation retrospectively reported in questionnaires reflects people's actual behavior. Addressing this research gap, we analyze the congruence oftime use information assessed through retrospective questionnaires and through experience sampling methodology. Participants completed standard survey questions on time allocation. In addition, a mobile-phone-based ...

A Household Study of Self-Regulation in Children: Intergenerational Links and Maternal Antecedents

Delay of gratification (DoG) and delay discounting (DD) are behavioral measures of self-regulation and impulsivity. Whereas DoG refers to the postponement of gratification, DD involves the devaluation of a reward over time. Previous studies have demonstrated associations between paternal self-control, paternal personality traits, parenting styles, maternal intelligence, and children's self-regulation. ...

The Role of the Log Transformation in Forecasting Economic Variables

For forecasting and economic analysis many variables are used in logarithms (logs). In time series analysis, this transformation is often considered to stabilize the variance of a series. We investigate under which conditions taking logs is beneficial for forecasting. Forecasts based on the original series are compared to forecasts based on logs. For a range of economic variables, substantial forecasting ...

The Dynamics of Repaet Migration: A Markov Chain Analysis

This article studies repeat or circular migration between the host and home countries using panel data for Germany, distinguishing between factors generating single moves, circular migration, and absorption. Migrants are more likely to leave early after their first arrival in Germany, and when they have social and familial bonds in the home country, but less likely when they have a job in Germany and ...

Naming and War in Modern Germany

This paper analyzes naming behavior in Germany in the context of rapid social change. It begins with an overview of general developments in naming in Germany over the last one hundred years, based on data from the German Socio-Economic Panel Study (SOEP), which supplies us with almost 45,000 datasets. The paper focuses on the periods of World War II and the Cold War since we conclude that general developments ...

The Complexity of Personality: Advantages of a Genetically Sensitive Multi-group Design

Findings from many behavioral genetic studies utilizing the classical twin design suggest that genetic and non-shared environmental effects play a significant role in human personality traits. This study focuses on the methodological advantages of extending the sampling frame to include multiple dyads of relatives. We investigated the sensitivity of heritability estimates to the inclusion of sibling ...
